DISPENSER FOR LIQUIDS AND OTHER MATERIALS.

Specification of Letters Patent.`

. Application filed April 18, 1911. Serial No. 621,765.

To all whom t may concern.'

`Be it known that I, FREDERICK R. Buss- LER, a citizen of the UnitedStates, and a resident of Quincy, in the county of Norfolk and State ofMassachusetts, have invented an Improvement in Dispensers for Liquidsand other Materials, of which the following description, in connectionwith the accompanying drawings, is a specification, like characters onthe drawings rep resenting like parts.

This invention is an improvement in dis pensers for liquid soap or othermaterials.

The character of the invention may be best understood by reference tothe ollowing description of an embodiment thereof appearing in theaccompanying drawing, wherein is shown in vertical section anillustrative dispenser embodying the invention.

Referring to the drawing, the illustrative dispenser there showncomprises a reservoir l of glass or other material provided at its upperend with an inlet opening 3 to permit filling of the reservoir, saidopening being normally closed by a cap 5 removably maintained on saidopening by resilient fingers 7 depending from said cap and engaging thewall of said opening.`

ln dispensers of the class described it is desirable to provide a devicewhich will deliver a small quantity or charge of the soap at a time inorder to prevent waste. .To this end herein the lower end of the res.ervoir is provided with a neckv9 containing a lining or 'bushing 11 ofnickel-plated brass or other material, said bushing having a flange 13for engagement with the outer end of the glass neck of said reservoi-rand a threaded portion at its inner end to receive a suitable nut l5thereby preventing saidV bushing from sliding outof said neck. Suit-`able askets 17 may be interposed between said ange and nut and theportions of the neck adjacent thereto. 'I he outer or flanged end ofsaid .bushing is threaded to receive the upper end of an air-tigl tdelivery cup or chamberlt) provided wit let herein in the form of anopening 21 in the bottom` of said cup.' `To control the discharge of theliquid from,\said reservoir a plunger 23 is provided having its upperend formed to have a sliding t in said neck bushing and its lower endreduced and ex- .tended through said cup outlet 2l to pro- Aliquid willbe from t 'an extent of the latter suiiicient forI effecftively closingthe entrance from said resera suitable out vide a handle 25 accessibleexteriorly of said cup for operating said plunger, as more fullyhereinafter described.' This handle is of a diameter substantiallysmaller than that of the outlet to permit the discharge of the liquidthrough said outlet around said handle. Adjacent said outlet is a flange2T projecting slightly upward in said cup and constituting a valve seatfor coperation with a valve, herein formed by a flange or shoulder 29 atthe juncture of the plunger with its handle and normally closing saidoutlet. To effect a non-leaking closure of the valve when on its seat awasher 3l of rubber or other suitable material is provided therefor. Theplunger 23 is normally thrust downwardly to maintain said valve on itsseat by a helical spring 33'encircling said plunger and having one endengaging said plunger flange and its opposite end engaging the outer endof said neck bushing. The upward movement of the plunger is limited bythe crowding together of the coils of the spring which encircle theplunger. the plunger' is held on its seat its upper end will be withinthe neck bushing and thus revented from flowing from said reservoir intothe chamber surrounding vsaid plunger, and also liquid in said chainberwill be prevented from escape through lthe outlet thereof. To convey apredetermined quantity or charge of liquid from the reservoir to saidchamber said plunger is providedwith a lateral recess, pocket or otherpassage 35 located a short distance e upper end of the plunger to leavevoir to said chamber. To sup ort the reservoir at its place of use abrac (et 37 may be 'fprovided having an attaching plate 39 at one endand a ring 4l at its outer end` ,threaded to receive the neck of thereservoir 1.

In `operation the outwardly rojecting plunger handle is pushed upwar vlyby the ypalm of the hand causing the plungerl pas- .'sage to advance uwardly toits dotted posi- Ition and communicate with the interior of:the reservoir. event liquid will iiow into said passage and on therelease of the-handle the plunger un- On the occurrence of this der theaction of its spring will be thrust downward and a charge of liquid willbe r When y roo t voir and chamberand edeotively preventsA on the valveseat.

said' valve seat, and expelled through the` chamber outlet, around thehandle and down along the latter into thel palm of the hand. Thehandle-in projecting through the'out-L let assists in conducting andguiding the liquid directly into the palm or the hand. Thus the repeatedoperation of the handle and its plunger as described takes charges fromthe reservoir and carries them bodily successively into the deliverychamber. At' ter the first charge has been delivered it will' not benecessary in obtaining the nextV charge to push the plunger upwardtwice, since a charge will always be in the cham? ber' in readiness tobe delivered therefrom on the first upward push of the plunger.

Heretofore, in liquid soap dispensers, con-- siderable difficulty hasbeen experienced fromthe drying and clogging 'of the delivery mechanism,owing, amongwther reasons, to the fact that such mechanisms have beenexposed to the air between operations. By my invention the` dischargingmechanism is not exposed to the air at any time excepting on' thedelivery of liquid therethrough since the mechanism is inclosed in theair-tight( 'chamber and the ingress of air thereto is ef-i fectivelyprevented by the sealing of the outlet end of the lchamber by theplunger valve As shown herein the liquid charge conveyedfby the plungerpas-f sage 35 is not sucient to completely ll the chamber surroundingthe plunger, but there isa volume of air pcketedabove the charge restingon the bottom of the chamber above its outlet. 'lhis constitutes a Huidseal beneath the'upper valve portion of the plunger which closes theentrance between the reserany leakage of liquid/from said reservoir pastsaid vplunger into said chamber. As a result the same volume of liquidcharge is always delivered from the chamber. .While 'herein both liquidand air are in the chamber it will be apparent that the seal would existif either air or liquid were in the chamber. Any tendency to dry or clogthe delivery mechanism is further prevented by the fact that saidmechanism is continuously sure rounded and kept wet by the liquid in thechamber. lf there should be at any time an accumulation of dry soapexterior of the valve seat in the annular discharge opening surroundingthe handle it is vautomatically dislodged when the -handlcl is movedupwardly for effecting a discharge operation.

Loraine A dispensersuch as described above provides a very advantageousconstruction; it is simple ih construction and operation, cheap tomanufacture and'is not liable to get out of order.

While the dispenser has been described herein as applicable forreceiving liquid soap, it will be readily understood that it may be usedfor delivering perfumery or other liquids or materials..
